WebbIn case of Yyn0d11 (or Yyn0d1), the buried delta will set up circulating current within Delta when there is current in one phase on secondary side. This will show up as current in two phases on primary side (for a single phase to ground fault on secondary side). The behaviour is similar to if it were Dyn instead of Yyn with buried Delta tertiary.

Webbof solid phases takes place as the temperatures gradually drop. It is important to understand the crystallization behavior of these mold fluxes used in the continuous casting of steel because the crystalline phase fraction in the slag films plays a crucial role in determining the horizontal heat flux during the casting process. WebbBackground. Lymphoid non-T cells that can kill virally infected and tumor cells were described more than four decades ago and termed natural killer (NK) cells. 1 NK cells can attack tumor cells without priming and their activity depends on a range of stimulatory and inhibitory receptors. 2,3 NK cells comprise about 5–15% of the human peripheral blood …
Webb10 okt. 2024 · In this study, by comparing the crystallinity and crystal phase morphology of the different basicities of mold fluxes after pulsed current treatment, it is found that a pulsed current increases the crystallinity of mold fluxes with low basicity but inhibits the formation of the crystalline phase of mold fluxes with high basicity.
